Give a House a Cookie — err, — Some New Plumbing

I’m quickly learning that there is no such thing as a small or contained project. A relevant example:

I’m in the midst of a bathroom renovation. One bathroom. But the way it keeps escalating reminds me of the well known children’s story, “If You Give a Mouse a Cookie.”

If you decide to gut a bathroom, you will probably decide to upgrade the plumbing.

If you need new plumbing in the bathroom, you should probably just replace the plumbing in the entire house.

While running new plumbing, you realize it’s the perfect time to replace the outdoor spigot and add a second spigot to the opposite side of the house.

When you want to run pipes to the kitchen, you realize the kitchen sink cabinet is actually metal, and the floor of this cabinet is nearly rusted away from years of leaking pipes. So if you are gonna re-plumb a house, you should probably tear out the deteriorating sink cabinet. Which means first lifting out the beautiful but extremely heavy cast iron sink.

And when you get to the laundry room with it’s somewhat “soft” floor, you should probably tear up the multiple layers of linoleum and punky plywood.

And once you have the bad flooring tore up, you realize that the original wood floor is too damaged to hold the weight and vibration of a full washing machine. So thats why if you are renovating a bathroom, you will probably need to replace the laundry room floor.

That is where the cute children’s story ends for tonight.

I finally have all of the old plumbing completely tore out, including the kitchen sink. I didn’t tear out all of these pipes right away, because it was kind of nice to use the old pipes as my straight line when running the new pex hose. The existing plumbing was a crazy labyrinth of galvanized, copper, pvc, and cast iron. And from how easily some of the connections came apart, I promise you it would have been leaking if the water was turned on.

For the new plumbing, I’ve got almost all of the new supply lines run. I now need to purchase a roll of red pex (for hot water) and run those lines to carry heated water to each of the shower, kitchen and bath sinks. The red and blue hose are entirely the same except color, but the color keeps things well organized.

I also need to make a decision on a new water heater. I’ve been researching tankless models, and I think I’ve decided on the ECO Smart brand. The prices are consistent with tank units, the reviews are good, and it seems very user intuitive. I can connect the water lines myself, but for the warranty to be valid, the electrical component must be wired by a licensed electrician.

And of course, supply lines are only half of a house’s plumbing. The other half is the drain pipes. The former mixed PVC, copper, and cast iron sections of drains had sections that had come unglued and weren’t sloped properly. Most of this I know how to do with new pvc, including traps and the correct pitch, and adding air vents for each the kitchen sink and washer drain. But the sewer stack that takes all the wastewater out of the house is the original cast iron. I’m not sure the best way to transition into this. So I’ll try asking friends for help, and if they don’t know, I wouldn’t be against hiring this part to make sure it is done perfectly correct, but it probably won’t be cheap.
